This is a stage where children absorb as much information as possible, the plasticity of their brain increases as the number of stimuli received daily, will be a stage where those things that did by reflection, begin to become habits, such as suction, the more habits you get, the more creation of neural networks continuously refining each action.

Exposing children to listen to different languages will make it easier for them to learn other languages in the future, each stimulus sent to the baby that is pleasant for them will allow them to acquire new skills and abilities that will be manifested later on.
